(02-11) 16:59 PST SAN BRUNO -- A Caltrain collided with a big rig Monday afternoon in San Bruno, causing major delays for the evening commute, authorities said.

The southbound train hit the truck near Angus Avenue, just north of the San Bruno station, around 2:30 p.m., when the truck failed to clear the intersection before the train rolled through, said Caltrain spokeswoman Christine Dunn.

No one was injured in the crash, and trains were stopped in both directions while San Bruno police investigated, Dunn said.

Trains are now single-tracking through the area and could continue to do so until 5:45 p.m. Riders should expect delays of 30 to 40 minutes in both directions during the evening rush hour, Dunn said.
